Diagnosis With Brief Discussion

Diagnosis: Primary cardiac lymphoma
Radiologic Findings: Fig 1. Chest radiograph shows the enlargement of the heart and no signs of pulmonary edema.

Fig 2-5. After pericardiocentesis, axial and coronal contrast-enhanced mediastinal window setting of chest CT scan shows a large mass that arises from the right atrium and extends into the SVC and right ventricle. The mass extends along the epicardial surfaces of the right atrium, encasing coronary artery. Pulmonary thromboembolism is also noted in both lower lobes.

He underwent surgical biopsy and pathologic result was diffuse large B-cell lymphoma. He made an additional systemic evaluation, and there was no evidence of lymphoma, except for the heart.
Brief Review: Lymphoma of the heart and pericardium is usually present as one aspect of disseminated disease and rarely occurs as a primary malignancy. It accounts for 1.3% of primary cardiac tumors and 0.5% of extranodal lymphomas. Cardiac lymphomas are most commonly diffuse large cell lymphomas and frequently manifest as an ill-defined, infiltrative mass. Atrial location is typical; the right atrium is most often affected. Pericardial thickening or effusion is often a common early feature of disease. Infiltration of atrial or ventricular walls with extension along epicardial surfaces is also a notable feature. At computed tomography, the attenuation of cardiac lymphoma may be similar to or lower than that of normal myocardium. At magnetic resonance imaging, it has variable signal intensity and contrast enhancement. Clinical manifestations may include pericardial effusion, cardiac arrhythmias, and a variety of nonspecific electrocardiographic abnormalities, notably first- to third-degree atrioventricular block. Treatment most commonly includes anthracycline-based chemotherapy and anti-CD20 treatment. Chemotherapy has been used alone or combined with radiation therapy. Palliative surgery has been performed, mainly for tumor debulking. The prognosis for patients with either primary or secondary lymphomatous heart involvement is usually poor; late diagnosis is one of the major factors affecting outcome.
